MACHINERY FOR SPREADING AND DRAWING FIBROUS MATERIEALS.

SPECIFICATION forming part of Letters Patent No. 497,237, dated May 9,1893.

Application filed September 28, 1892.

To aZZ whom. it may concern:

Be it known that I, JOHN GOOD, a resident of Far Rockaway, inthe countyof Queens and State of New York, have invented a new and usefulImprovement in Machinery for Spreading and Drawing Fibrous Materials, ofwhich the following is aspecification.

The object of this invention is to obtain in one machine by a continuousoperation, a sliver of such quality as by the machinery heretofore usedhas required several machines and several separately performedoperations to produce it.

I will first describe in detail a machine embodying my invention andafterward point out its novelty in claims.

Figure 1 represents a central vertical section of the machine and Fig. 2a plan of the same.

Similar letters of reference designate corresponding parts in bothfigures.

A A designate the framing of the machine.

B B B B are four trains of gill-pin bars armed with gill-pins b b b band carried by sprocket wheels on shafts o o* c 0 c 0 c 0 which work inbearings on the framing A A. These trains are arranged one beforeanother. The two trains B B are of the same character commonlyemployedin spreaders as for example, in the spreader which is the subject of myLetters Patent No. 95,462, dated October 5, 1869, the second train 13running much faster than the first train B. The two trains B and B areof similar character, the fourth train B running much faster than thethird one B but they have their pins finer and closer together, and theymay be as represented in Fig. 2, narrower than the first and secondtrains B B The third train B may run somewhat faster than the second13*, but must not run slower. The third train 13 is set sufficiently inadvance of the second B to make room between them for a conductor Owhich consists simply of a flat board having upwardly projecting sides aa which converge laterally toward the end of the board nearest the thirdtrain B Between this conductor and the second train B there isrepresented a pair of delivery rollers e e to take the fiber from thesecond train of pins and denial No. 447,187. (No model.)

deliver it tothe conductor, and between the conductor and the thirdtrain there is represented a pair of feed rollersff to take the fiberfrom the conductorand give itto the third train of pins. The deliveryrollers 6 should run at a speed about the same as but not slower thanthe second train B and the feed rollers f at a speed about the same butnot slower than the delivery rollers e, and not faster than the thirdtrain B In rear of the first train of pins there is a pair of feedrollers g and in front of the fourth train there is a set of deliveryrollers h. There is also represented in front of the delivery rollers acondenser D.

The machine is represented as driven by a driving shaft E (Fig.2) whichworks in bear: ings in stands E. On this shaft is a pulleyz from whichruns abelt to a pulley 7e on the shaft h of one of the delivery rollersh. The shaft it carries also a spur gearZ which gears with and drivesone of two spur gears m n which are fast together and turn on a stud onthe framing, the other of said two gears gearing with a spur gear 0 on.the shaft 0 of the fourth train of gill-pins B and so driving the saidtrain. The shaft 0 of this train 13* carries a spur gear 10 which gearswith one of two spur gears q r which are fast together and turn on astud on the framing, the other of said two gears gearing with a spurgear 3 on the shaft 0 of the third train B and so driving that train,the shaft 0 of which is geared in a suitable manner with thafeed rollersf to drive the latter. The driving shaft E carries also a spur pinion itwhich gears with a spur gear a on the shaft of one of the deliveryrollers e, and so drives the said roller which also carries a spur geara which gears with and drives a spur gear 21 turning freely on a stud onthe framing and gearing with a spur gear 20 on the shaft 0 of the secondtrain B of gill pins and so driving the said train. The shaft 0 of thistrain carries a gear a: which gears with and drives one of two spurgears 00' 00 fast together and turning on a stud on the framing, theother of said two gears gearing with a gear g on the shaft 0 of thefirst train B of gill-pins and so driving the said train the other shaft0 of which carries a gear 2 which is geared in a suitable manner withand drives the feed rollers g.

The several gears and pulleys hereinbefore described are relatively soproportioned that the trains are respectively driven at the speedshereinbefore mentioned.

G G are two feed-boards upon which are to be placed two separate layersof fiber to be collectively supplied to the feed rollers g to be fed tothe first train of gill-pins. The board Gis arranged in the way commonto that of the single feed-board commonly employed in machines forspreading and drawing hemp and other fibrous materials, thatis to say,it is behind and has a downward inclination toward the feed rollers g,its lower end being opposite the opening between the said rollers sothat the fiber deposited upon it may pass from it directly between saidrollers. The-board G faces the board G,being arranged over the firsttrain of gill-pins B with a downward inclination in the oppositedirection to that of G, and its lower end terminates close above thefeed rollers g. The layer of fiber deposited on this board G hasto passover the top of and round the back of the-upper feed roller to enterbetween the feed rollers, its entrance being above that of the layerfrom G, as the two layers enter collectively between the rollers.

The operation of the machine is-as follows: The two layers of fiberdeposited upon the two feed-boards and carried between the feed rollersare deposited collectively one superposed above the other upon the firsttrain of gill-pins B, by which they are carried forward to the secondtrain 13 a spreading operation taking place in a well known manner uponand between these trains, the single lap of fibers thus produced beingdelivered by the rollers 6 upon the conductor O above which it passes tothe feed rollers f. In passing along the feed board thelap is contractedlaterally by the tapering sides of the said board and is therebythickened before being received between the feed rollers f which give itto the third train B by which it is carried forward to the fourth trainB A second spreading operation takes place upon and between the thirdand fourth trains of pins and the lap taken from the fourth train by thedelivery rollers h passes on to the condenser D in which it is convertedinto a sliver.

In the above operation the two layers of fiber superposed upon the firsttrain of pins are more uniformly distributed than would be possible witha single layer of the same volume and hence a more uniformly spread thinlap is obtained from the second train, and this lap being contracted inwidth in passing through the conductor 0 is delivered to the third trainwith sufficient body or thickness to be properlysubjected to theoperation of the pins of this and the fourth train by which it is againspread so that the resulting sliver delivered from the condenserD isvery even and of very uniform thickness and quality.

What I claim as my invention is- 1. The combination of four endlesstrains of gill-pin bars and gill-pins thereon arranged one train beforeanother the third and fourth trains having their pins set closertogether than the pins of the first and second, mechanism for drivingsaid trains all in the same direction the second train faster than thefirst the fourth faster than the third and the third not slower than thesecond, a feeding device for feeding fiber to the first train, aconductor with laterally converging sides between the second and thirdtrains and a delivery apparatus for taking the fibers from the fourthtrain, substantially as herein set forth.

2. lhe combination with an endless train of gill-pin bars and gill-pinsthereon and a pair of vfeed rollers for feeding fiber to said gillpins,of two feed-boards arranged facing each other for a double supply offiber to said pair of feed rollers,substantially as herein set forth.

JOHN GOOD.
